IMPROVEMENT IN UMBRLLAS TheSchedu1e referred to in these Letters Patentand making part o the same.

To allwhom it may concern:

Be it known that I, DURWARD ADAMS, of Boston, in the county of Suffolk,and Stute of Massachusetts, have invented en Improvement in Umbrellasand Porasols, of' which the following is a full, clear, und exactdescription, reference being had to the accompanying drawings makingpart of this specification, in which- Figure 1 is acent-rul verticalsection, representing my improvement applied to an umbrella when openand ready for use.

Figure 2 is :t central vert-ical section through a closeduinbrellzushowing the position or relation of my improvement theretojust previous to its being opened.

Figure 3 represents the position ofr my improvement .when the umbrellaIis to be set :iside und is not required for use. l

My invention hes for its object to provide an urnbreilu. or parasolwhich shall instantly spring open when required, by means ot' elasticrubber springs or bonds; and v My invention consists in the applicationof rubber springs leading from the stud' or handle, or asleeve thereon,to the breces or runner, or both, the springs being dstended whentheumbrella. or parasol is closed, so that when the catch is pressed in,the runner will he drawn up andu the braces thrown out by the recoil ofthe springs, thereby opening the cover as required.

Toeneble others 'skilled in the art to understand und use my invention,I will proceed to describe the manner in which I have carried it out.

In the said drawings- A is the stuff or handle, B B the braces, C G theribs, D the cover, E the runner, G the lower catch, and H the uppercatch, ull constructed in e well-known manner.

I I are rubber springs, one end of each of which is secured by a ring orotherwise to one ofthe braces B, the opposite end of the spring beingsecured to e. sleeve,

K, surrounding the staff or handle A, the sleeve being heldin place bye, catch, a.

J is also a. rubber spring, one end of which is secured tothe sleeve'K,while its other end, instead of being secured to one of the braces, isconnected dlrectly with the runner.

When the umbrella is closed, the springs I J are distended and held inthis position (see fig. 2) by the lower catch G, which passes throughthe side of the runner E.

On pressing in the lower catchA the runner is released, when the recoiloi' the springs IJ willinstently draw it up and throw out the braces BB, thereby opening the umbrella without the necessity of' employing bothhands, as heretofore.

To relieve the tension on the springs when the umbrellzt is to be setaside und is not required for immediste use, it is simply necessary topress in the catches H and a and slide the sleeve K over them, when itwill be drawn down by the closing of the umbrella. without extending thesprings.

Instead of employing a sliding sleeve, K, the springs muy beA secureddirectly to the handle, their opposite ends being secured to the bracesand runner by means of hooks, which `rnny readily be detached when theumbrella is to be set aside.
